Asus HD4850 MEMIO reaches threshold

[enigmajk]

Hello, my video card has just recently started to give me problems. To start out when I first bought my video card it would give me VPU errors 5 minutes into any graphics intensive game, (Crysis,TF2,COD5). I searched for a solution and found multiple answers, only two of these solved it. I had to enable manual fan speed, which helped somewhat with temps, then, I had to increase my voltage from 1.082 to 1.120 via ATI Tray Tools. Which also increased my temps even more.

This fixed my problem for probably 6 months. I only ran into occasional VPU errors and sometimes my video card would shut off during games. But now I get them anywhere from 30 minutes to an hour into a game (recently L4D). So, I ran Furmark and let it run for about 10 minutes, during that time my video card shut off completely. So, I open my case during this time and notice a red led on the backside of the card. After I examined it further I noticed D1601 next to it(A quick search brings up a list of Diagnostics), indicating that my temps had reached threshold.

Upon reboot I opened my GPUz log and saw that at the time of my video card shutting down the MEMIO temp had reached 115C (Threshold). Should I RMA this card or could it be something else? If I was to RMA how long would it take to get it back? I was thinking of just getting a cooler for it so I dont have to wait 4 or 5 weeks just to get my card back.

For reference my video card is the ASUS Top Edition HD4850. This one.

I'd RMA it...sounds like it's faulty. Looking at newegg customer reviews though...it seems other people have the same issue and some have had the issue with their RMA cards as well.

Your card is probably overheating. MEMIO temp is the memory controller temperature on the GPU and 115 C is a lot. Try cleaning the heatsink, see if the fan is spinning or if the heatsink it's attached as it should. What I don't understand is why have you increased your voltage from 1.082 to 1.120V? 1.120 V is the stock 4850 voltage and it should not be lower then that.

It should have lower voltage&clocks when idle.. ATT will show the clocks/voltage of the mode that was on when the "overclock" panel was opened.. the values set will however stick in both modes, once set.

I had two 4870 and none of them had any voltage decrease during idle. You can do it manually, but it's not going to do it itself. And, I really don't think 4850 does it either.

Well, mine was set to 1.082 whether it was the idle voltage or not (I cant remember) I had to increase it. Today, I tested Furmark with a boxfan blowing on the video card and it ran perfectly 30 minutes, no problems. The memio temps only reached max 105c during this time.
I am almost tempted to just buy a cooler and not deal with ASUS support, from what I have been reading asus support isnt that great.

I think that is too high. I say RMA it and only change the cooler if you have the same problem again.

I think those MEMIO temps are likely normal because when I had my 4870 1GB (reference), it would hit 115C on the MEMIO and 119C on one of the 3 VDDC sensors under load (extended gaming, not furmark) while sounding like a jet engine at the same time:roll:.

But it does sound like you likely need a RMA. The RMA should probably take around 3-5 weeks, so you might want to have another temporary card handy if you plan to use that computer during that time.

I'm not sure how long Asus takes but my Gigabyte motherboard was back to me in about 2 1/2 weeks.

I remember TechReport complained about that cooler. Will try to find the link for you.

Edit: Here

We first noticed this problem during our performance testing, when our test system would lock up at random. There wasn't any particular pattern to it, except that we could run a game for while on it without issue, but eventually, inevitably, the screen would go black and the system would lock. Once we started troubleshooting with a eye toward a thermal issue, the problem became clear almost immediately. We didn't even have to make use of both GPUs. So long as a second card was nestled up against the Asus 4850, the Asus would overheat in a matter of minutes. You could watch it happening. Temperatures would rise, the card's fan speed would peak, and GPU temps would continue climbing. Eventually, within five to ten minutes, the temperature would climb past the 100°C mark, and shortly thereafter, the screen would go blank. Bam. Game over.
